Residual current transformers, 105 mm Ø (inner), Type A, AC

Residual current transformers are used in combination with evaluation units to monitor and protect electric circuits. Series DCT transformers combine with DMRCD evaluation units to form modular residual current devices (MRCDs) as per EN 60947-2 or with DRCM evaluation units to form residual current monitors (RCMs) as per EN 62020. Only components of the same type of residual current (A or B+) can be combined. Residual current transformers with characteristic A detect sinusoidal AC currents as well as pulsating DC residual currents. The transformer covers all of the active conductors leading to the consumers and uses its output signal to illustrate the time curve of the sum of all conductor currents flowing through it. Its output signal is proportional to the residual current, which flows back to the earthing point of the supply mains via the protective earth conductor in the case of an insulation fault or via the earth.

suitable for detecting residual currents type A and AC, monitored frequency range 50 Hz - 60 Hz (type A) 40 Hz - 2 kHz (type AC), detection of rated residual operating current and residual current of 30, 100, 300, 1000 and 3000 mA, available designs with internal diameters of 20, 30, 35, 70, 105, 140 and 210 mm, rated voltage of monitored circuit up to 690 V, for rated currents up to 400 A, rated current can be extended using DMBT centring sleeve, compact, robust plastic housing, easy mounting

The devices are mounted on stable substrata using the supplied mounting brackets.any installation position

Transformers from series DCT A are used in conjunction with residual current monitors from series DRCM type A and modular residual current devices from series DMRCD type A.

The residual current transformers as bushing transformers are only permitted for operation with insulated cable and line systems. The internal diameter of the transformer must be set to at least 1.5 times the size of the external diameter of the cable(s) to be wired.
